Flex Couplings are an affordable and durable option for reducing vibration and stress in an exhaust system.
Our slip-fit Interlock Liner style Flex Couplings feature 100% 304 Stainless Steel construction and including the end caps, and provide a smooth and uninterrupted flow for high temperature exhaust gasses. Each Interlock Liner style Flex Coupling contains an external braided section, an internal flex bellow, and an interlock style liner that can withstand the high temperatures of a forced induction exhaust system.
Note, Flex Couplings are not recommended for pre-turbo installation — try our Flex Bellows for pre-turbo installation!
